In the crystal structure of the title compound, [Ag(NO₃)(C₁₅H₈N₂O₂)₂], tryptanthrin (indolo[2,1-b]quinazoline-6,12-dione) and silver nitrate form a 2:1 complex. The silver ion is surrounded by two tryptanthrin ligands, each coordinating through the N atoms, with Ag—N bond lengths of 2.247 (3) and 2.264 (3) Å, and an anionic nitrate ligand coordinating through two O atoms, with Ag—O bond lengths of 2.499 (3) and 2.591 (3) Å. The N—Ag—N plane and the O—Ag—O plane are roughly perpendicular, making a dihedral angle of 81.6 (2)°. In the crystal, C—H⋯O interactions between aromatic H atoms and keto and nitrate O atoms as well as π–π interactions [centroid-centroid distance = 3.706 (4) Å] give rise to a three-dimensional network.

Comment top

Tryptanthrin is an indole quinazoline alkaloid isolated from Folium Isatidis (Chen et al., 2011). It was found to inhibit the murine myelomonocytic leukemia cells by causing cell cycle arrest and triggering cell differentiation (Chan et al., 2009), and reverse the doxorubicin resistance in breast cancer cells by inhibition of MDR1 (Yu et al., 2007). It was also found to inhibit the growth of Escherichia coli through intercalation into DNA (Bandekar et al., 2010). In addition, synthesis of tryptanthrin (Kumar et al., 2011) and its derivatives (Chen et al., 2011) were reported.

Tryptanthrin and silver nitrate form a 2:1 complex. The same proportions were used in the synthesis. Both the two tryptanthrin molecules are essentially planar with mean deviations of 0.0066 (4) Å and 0.0054 (3) Å, respectively, and make a dihedral angle of 2.9 (2)°. The nitrate group makes dihedral angles of 89.5 (3)° and 105.1 (4)° with the two tryptanthrin molecules. The silver ion is coordinated with two oxygen atoms from the anionic nitrate ligand with bond distances of 2.499 (3) Å and 2.591 (3) Å, and two nitrogen atoms from the tryptanthrin ligands with bond distances of 2.266 (3) Å and 2.249 (3) Å, which are slightly longer than those reported in silver nitrate complex with 4,4'-trimethylenedipiperidine [2.192 (5) Å and 2.212 (5) Å] (Kokunov et al., 2011). The N—Ag—N plane and the O—Ag—O plane are roughly perpendicular with a dihedral angle of 81.6 (2)°. The bond distances and bond angles in both tryptanthrin molecules are all normal (Allen et al., 1987).

Short intermolecular C—H···O interactions (Table 1) between the tryptanthrin methane H atoms and the nitrate ligand [C4'—H···O4, 3.300 (3) Å, C13'—H···O4, 3.453 (2) Å] linked adjacent molecules into layers. Adjacent layers were linked by π-π interactions between the benzene rings [centroid-centroid distance 3.706 (4) Å and displacement angle 4.5 (2)°]. The centroid-centroid distance observed in title compound is similar to those in natural flavonoids (Jiang, et al., 2002 and 2009).

Experimental top

Tryptanthrin (12.4 mg, 0.05 mmol) was dissolved in a solution including methanol (1 ml) and chloroform (3 ml). silver nitrate (17.0 mg, 0.1 mmol) was dissolved in methanol (1 ml) and was added into the tryptanthrin solution. Three days later, the crystals were obtained via slow evaporation at room temperature.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
